Germany Application January 13, 1933, Serial No. 651,555, and in Germany September 27, 1932 4Claims.

This invention relates to a mount for pictures, photographs and the like between two sheets formed for example by a folded sheet, the upper sheet having an aperture for the picture and its facing surfaces being provided with an adhesive substance which, after smearing with a solvent, such as water, enables the under and upper sheets to be stuck together. In the known devices the surface of the under sheet facing the aperture sticks tightly to the inserted picture so that the picture becomes distorted or is affected by chemical or physical influences, which is just that which it is desired to avoid; The surface of the under sheet opposite the aperture might have a recess in the size of the picture to be inserted, in which recess the adhesive coating is interrupted by some means or other. It would require very careful work to fix the picture in such a mount without the moistened or dissolved adhesive substance coming into contact with the picture. In many instances the picture is larger than the aperture in the upper sheet and it is scarcely possible to adapt the space free from adhesive substance to the size of every picture. Consequently the under sheet stuck on to the back of the upper sheet must surround the picture on all sides so that it cannot slip even slightly between the two sheets stuck one on the other.

According to the invention the adhesive coating on the facing surfaces of the sheets consists of a known dry adhesive substance which only sticks when the two coated surfaces lie directly the one on the other.

It is known, for example, to providepost-cards for typewriters with a so-called dry adhesive substance. The post-cards can be written as desired on the typewriter without sticking because a portion coated on one side with such an adhesive substance cannot stick. Only when the card has been typed and the portion bearing the address is bent on to the back of the card, it will stick because two surfaces coated with the dry adhesive substance lie one against the other.

By employing such a. dry adhesive substance, which only sticks when two surfaces similarly or dissimilarly coated bear one against the other, it is possible to clamp a picture between the two sheets so strongly that the picture cannot shift out of the range of the aperture or relative thereto. Moreover, the picture is not stuck in any way so that after tearing 011 the mount sheets it lies absolutely free and it cannot be chemically or physically affected .because it is easy to prevent the adhesive substances from adhering to or penetrating through the picture.

It is evident that there is nothing to prevent the picture from being protected by means of a layer, such as wax sheet or the like so that the adhesive substance cannot possibly chemically or physically affect the picture.

The above described mount for fixing pictures, photographs and the like between two sheets provided with dry adhesive substance can be employed in various manners. In the case of pictures which are to be visible through the sheets, as it is not necessary to provide apertures in the sheets. In the case a picture is to be exposed in the top sheet a corresponding aperture must be provided in this sheet. If the picture is to lie freely and to be regarded against the light, as in the case of a diapositive, a Rontgen film or a coloured film, registering apertures are to be provided in both sheets. For fixing film-like stereoscopic diapositives two apertures must be provided in each sheet. Consequently, the mount is suitable for a large number of different purposes.

Three embodiments, of the invention are illustrated by way of example 'in the accompanying drawing in which:--

Fig. 1 shows the inner side of a mount for an opaque pictures.

Fig. 2 shows the picture to be mounted.

Fig. 3 represents the picture fixed'in the mount.

Fig. 4 shows the inner side of a mount for transparent pictures.

Fig. 5 shows a transparent picture.

Fig. 6 represents the transparent picture fixed in the mount.

Fig. 7 represents a stereoscopic picture fixed in a mount.

In the drawing 1 and 2 designate two sheetsmade of paper, cardboard or the like which are preferably formed by folding a large sheet on the line 3. The sheet 1 has an aperture 4 which corresponds in shape and size to the portion of the picture which is to remin visible. The adiacent surfaces of the sheets 1 and 2 are then coated with a so-called dry adhesive substance. A surface coated with such an adhesive substance does not stick tightly to any article or another surface even if it contains a high percentage of'moisture. Only when two surfaces coated with such an adhesive substance are brought into contact do these surfaces stick tight! ly. Consequently, as soon as the surfaces 1 and 2 lie one on the other, they adhere tightly. Therefore, if the picture 5 (Fig. 2) is placed on the sheet 1 with its front side visible through the aperture 4, its edge 6 does not stick thereon. Only when the sheet 2 is folded over and pressed against the sheet 1 will the two sheets adhere tightly the one to the other, but the sheet 2 will I not stick to the back of the picture. The picture g and 2 like the mount shown in Fig. 1, each sheet being however provided with an aperture, the

consequently lies absolutely loosely between the two pasted sheets 1 and 2 and even if these two sheets are torn apart it is nowhere stuck thereto.

At the same time thesheets 1 and 2 stick together so accurately around the edge of. the picture 5 that, although the picture is loose, it lies absolutely unshiftable between the sheets.

It is evident thatthe sheets 1 and 2 need not be connected and folded 'on the line 3but may be separate the one from the other and connected after'the insertion of the picture 5. The sheet 1 may be embossed or provided with decorative designs and the like, both sheets may be perforated or provided with some holding devices to enable pictures thus mounted to be arranged in an album or other arrangement. There is likewise no reason why these sheets should not be constructed so that they can be provided with inscriptions, descriptions and notes concerning the picture, which is often the object of such mounting.

In Fig. 4 the mount is formed of two sheets 1 sheet 1 having an aperture 7 and the sheet 2 an aperture 8. The frame-like portions of the sheets 1 and 2 are coated with a dry adhesive substance, exactly as above described in connection with Fig. 1. A fold 3 is provided between the sheets 1 and 2 as in Fig. 1. The Rontgen picture 9 illustrated in Fig. 5 can be advantageously provided with a narrow border 10. If the transparent picture 9 which evidently might also be a diapositive, a coloured film or the like is laid in the mount in the manner described in connection with Figs. 1 to 3, a picture 9 is produced surrounded by a frame as shown in Fig. 6. This picture is fixed just as securely as the picture in Fig. 3, but can be viewed against the light'a's a transparent picture.

In the construction shown in Fig. 7 each sheet 11 is provided with two 'apertures 12 and 13, in which, for example stereoscopic diapositives can be mounted in order to be viewed in a stereoscope. If the mount is to be used for opaque pictures,

one sheet is provided with two apertures 12, 13 instead of one as in Fig. 1, but if transparent pictures are to be mounted therein, each sheet is provided with two apertures, so that the mount in open condition appears similar to that shown in Fig. 4, only in this instance two apertures are provided in the place of each of the apertures I claim:--

-1. A mount for pictures, comprising in combination a picture backing sheet, a' picture covering sheet having a window, and a coating of dry adhesive on said backing and said covering sheet, said adhesive adhering only to surfaces coated with a similar adhesive and adapted to protect against sticking the edge portion of the picture inserted between said backing and said covering sheet.

2. A mount for pictures, comprising in combination a picture backing, a picture covering sheet having windows, and a coating of dry adhesive on said backing and said covering sheet, said adhesive adhering only to surfaces coated with a similar adhesive and adapted to protect against sticking the edge portion of the pictures inserted between said backing and said covering sheet.

3. A mount for pictures, comprising in combination a picture backing having a window, a picture covering sheet having a window corresponding to the window in said backing, and a coating of dry adhesive on said backing and said covering sheet, said adhesive adhering only to surfaces coated with a similar adhesive and adapted to protect against sticking the edge 'portion of the picture inserted between said backing and said covering sheet.

4. A mount for pictures, comprising in combination a picture backing having windows, a,

picture covering sheet having windows corresponding to the windows in said backing, and a coating of dry adhesive on said backing and said covering sheet, said adhesive adhering only to surfaces coated with a similar adhesive and adapted to protect against sticking the edge por- FRIEDRICH KosTER.
